Background: Primary open-angle glaucoma (POAG) is affected by both genetics and environmental factors. CDKN2B-AS1 polymorphisms have been reported to be involved in the pathogenesis of POAG. However, the results of the genetic associations between the CDKN2B-AS1 polymorphisms and POAG risk were inconclusive.
Aims: This study aimed to evaluate the correlation of CDKN2B-AS1 polymorphisms and POAG susceptibility using a meta-analysis.
Methods: Meta-analysis was performed by searching PubMed, Web of science, the Cochrane database of system reviews, CNKI, and Embase databases. The relationship of CDKN2B-AS1 rs4977756, rs10120688, rs2157719, and rs7049105 polymorphisms and POAG risk was evaluated by the odds ratios (ORs) and 95% confidence intervals (CIs).
Results: Eleven studies with 8290 cases and 13,485 controls were included in the present meta-analysis. The alleles of rs4977756 and rs10120688 significantly increased the risk of POAG (rs4977756: OR = 1.20, 95%CI = 1.03-1.39, p = 0.02; rs10120688: OR = 1.36, 95%CI = 1.29-1.44, p < 0.00001). As for ethnicity, rs4977756 polymorphism significantly increased POAG risk in Caucasians (OR = 1.33, 95%CI = 1.12-1.57, p = 0.0009), but not in Asians. In addition, the rs2157719 allele was significantly associated with POAG risk in Asians (OR = 0.66, 95%CI = 0.55-0.80, p < 0.0001), but not in Caucasians (p > 0.05).
Conclusions: The CDKN2B-AS1 rs4977756 might increase the POAG risk in Caucasian population, and rs2157719 might decrease the POAG risk in Asian population, while rs10120688 might increase the risk of POAG.

Article Synopsis
- This paper presents a new method using GWAS filtering to identify novel phenotypes associated with genetic loci, focusing on cardiovascular disease (CVD) using UK Biobank data.
- The study employs an automated routine to analyze associations between various phenotypes and single nucleotide polymorphisms (SNPs), identifying six gene variants linked to CVD that work independently of known risk factors.
- The research not only highlights new gene-phenotype associations but also explores potential mechanisms explaining how these genetic variants contribute to cardiovascular disease.
The mechanisms of Chr.9p21.3 risk locus in coronary artery disease: where are we today?

Despite the advancements and release of new therapeutics in the past few years, cardiovascular diseases (CVDs) have remained the number one cause of death worldwide. Genetic variation of a 9p21.3 genomic locus has been identified as the most significant and robust genetic CVD risk marker on the population level, with the strongest association with coronary artery disease (CAD) and other diseases, including diabetes and cancer.

Article Synopsis
- Genetic variants of long noncoding RNAs, specifically SNPs in CDKN2B-AS1, are linked to cancer risk and progression, with a focus on prostate cancer (PCa) in this study.
- Five SNPs were analyzed in a case-control study of 695 PCa patients and 695 healthy individuals, revealing that the rs1333048 variant increases the risk of developing aggressive tumors.
- Higher expression levels of CDKN2B-AS1 were found in individuals with the C allele of rs1333048, which correlated with larger tumors and worse outcomes, suggesting that this variant could influence the progression of prostate cancer.
Causal relationships of familial hypercholesterolemia with the risk of multiple vitamin deficiencies: a Mendelian randomization study.

National Drug Clinical Trial Center, The First Affiliated Hospital of Bengbu Medical University, Bengbu, Anhui, China.
Article Synopsis
- This study explores the connection between familial hypercholesterolemia (FH) and vitamin deficiencies, seeking to clarify if having FH increases the risk of these deficiencies.
- Utilizing Mendelian randomization, researchers analyzed extensive datasets from the FinnGen study, focusing on FH, ischemic heart disease, and various vitamin levels among over 300,000 individuals.
- The findings suggest that FH is linked to higher odds of thiamine and vitamin D deficiencies, highlighting potential complications arising from FH that may impact individuals' health.
Amlodipine increases risk of primary open-angle glaucoma.

Severn Health Solutions, Severna Park, MD, USA.
Article Synopsis
- Calcium channel blockers, specifically amlodipine, have been found to increase the risk of developing primary open-angle glaucoma (POAG) by 23%, prompting a study to further explore this association and its genetic factors.
- An analysis using MedWatch and UK Biobank data revealed that amlodipine use was linked to a significant rise in POAG prevalence and identified specific genetic polymorphisms (GAS7, CDKN2B-AS1, SIX6) that contribute to this risk.
- The study concluded that while amlodipine is commonly used for hypertension, its potential connection to POAG emphasizes the need for healthcare providers to consider alternative medications to minimize this risk.
